WCF中的Selenium Firefox WebDriver抛出“未能在45000毫秒内启动套接字". [英] Selenium Firefox WebDriver in WCF throwing "failed to start up socket within 45000 ms"

问题描述

异常堆栈跟踪:

OpenQA.Selenium.WebDriverException:无法在45000毫秒内启动套接字.尝试连接到以下地址:127.0.0.1:7055 在OpenQA.Selenium.Firefox.FirefoxDriverServer.ConnectToBrowser(TimeSpan timeToWait) 在OpenQA.Selenium.Firefox.FirefoxDriverServer.Start() 在OpenQA.Selenium.Firefox.FirefoxDriverCommandExecutor.Execute(Command commandToExecute) 在OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute，Dictionary'2 parameters) 在OpenQA.Selenium.Remote.RemoteWebDriver.StartSession(ICapabilities wantedCapabilities) 在OpenQA.Selenium.Remote.RemoteWebDriver..ctor(ICommandExecutor commandExecutor，ICapabilities requiredCapabilities) 在DtvAutomation.Selenium.Api.SeleniumFirefoxTest.CreateWebDriver() 在DtvAutomation.Selenium.Api.SeleniumTest'1.Run()

OpenQA.Selenium.WebDriverException: Failed to start up socket within 45000 ms. Attempted to connect to the following addresses: 127.0.0.1:7055 at OpenQA.Selenium.Firefox.FirefoxDriverServer.ConnectToBrowser(TimeSpan timeToWait) at OpenQA.Selenium.Firefox.FirefoxDriverServer.Start() at OpenQA.Selenium.Firefox.FirefoxDriverCommandExecutor.Execute(Command commandToExecute) at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary'2 parameters) at OpenQA.Selenium.Remote.RemoteWebDriver.StartSession(ICapabilities desiredCapabilities) at OpenQA.Selenium.Remote.RemoteWebDriver..ctor(ICommandExecutor commandExecutor, ICapabilities desiredCapabilities) at DtvAutomation.Selenium.Api.SeleniumFirefoxTest.CreateWebDriver() at DtvAutomation.Selenium.Api.SeleniumTest'1.Run()

引发异常的代码正在调用Firefox WebDriver构造函数:

The code that throws the exception is calling the Firefox WebDriver constructor:

protected override FirefoxDriver CreateWebDriver()
{
    lock(this.syncRoot)
    {
        var ffBinary = new FirefoxBinary();
        var ffProfile = new FirefoxProfile();
        return new FirefoxDriver(
            binary: ffBinary,
            profile: ffProfile,
            commandTimeout: TimeSpan.FromMinutes(2));
    }
}

我正在使用Visual Studio 2013-"WCF应用程序服务"项目中的硒2.46(通过NuGet程序包). Firefox是38.0.5(最新). 当我从Visual Studio(调试模式)启动WCF时，一切正常，没有例外.当我将WCF发布到本地IIS时，会引发此错误.

I am using selenium 2.46 (via NuGet package) from a Visual Studio 2013 - "WCF Application Service" project. Firefox is 38.0.5 (latest). When I start the WCF from Visual Studio (debug mode) everything works fine - no exceptions. When I publish the WCF to local IIS it throws this error.

我尝试了以下操作:

• 更新的NuGet软件包-确保我是最新的
• 将Firefox降级到版本34.0.5
• 将Firefox升级到最新版本
• 从防火墙打开了端口7055
• 使用管理员帐户更改IIS应用程序/应用程序池的凭据
• 在例外情况下，请尝试使用其他端口初始化WebDriver

这些似乎都不起作用. 有任何想法可能是什么问题吗?

None of these seem to work. Any ideas what could be the problem?

推荐答案

我遇到了同样的问题.将应用程序池标识更改为LocalSystem之类的问题可以解决此问题，但是您不想在生产中这样做.

I had the same issue. Changing the app pool identity to something like LocalSystem solved the issue, but you don't want to do that in production.

相反，我在应用程序池的高级设置"中找到了一个设置为False的设置LoadUserProfile.如果将其设置为True，则应用程序池将加载用户配置文件，从而消除了Selenium问题.

Instead I found a setting, LoadUserProfile, on the Application Pool's Advanced Settings, that was set to False. If you set it to True, the application pool loads a user profile which in turn gets rid of the Selenium issue.

您至少需要运行IIS 7，并且可以阅读有关设置的更多信息

You need to run at least IIS 7, and you can read more about the setting here.
